I installed the module on our site and on the Windows 7 desktop, but there is no data being fed to the widget. The widget itself is installed, just no data. BTW, 99% of Vista widgets run fine on Windows 7, so assuming that's not the problem.

I can definitely browse the page fine. However, the only thing I find in the scheduler regarding the Users Online module is this entry:

DotNetNuke.Entities.Users.PurgeUsersOnline, DOTNETNUKE

I'm not sure if that's sufficient or not. Please note, that we have the both the regularUsers Online module (and Where Are They?) , as well as the Vista Users Online version of your applications installed. Would that cause a conflict?
